WHEELED PLOW.

Specification of Letters Patent.

Patented Mar. 4, 1919.

Application filed May 4, 1915. Serial No. 25,665.

To all whom it may concern:

Be it known that I, OTIS W. HOWARD, a citizen of the United States, residing at Moline, in the county of Rock Island and State of Illinois, have invented certainnew and useful Improvements in Wheeled Plows, of which the following is a specification, refhad therein to the accompanying drawing.

My invention relates to wheeled plows and particularly to the means employed to lower the plows for operation, and to raise them from the ground whenever it is desired.

The object of my invention is to provide a simple and effective lever mechanism for raising and lowering a plow with a minimum of exertion on the part of the driver, and which will be automatically locked in eitherposition and heldsecurelyagainst accidental unlocking.

A still further object of my invention is to simplify and condense the mechanism by which the plows are lowered or raised. Other objects will be disclosed in the following specification. 7

Referring tothe drawings in which similar numerals indicate identical parts- Figure 1 is a plan view of a wheeled plow embodying my improvements.

Fig. 2 is a side elevation of Fig. 1 with the plows raised and the land wheel removed.

Fig. 3 is a side elevation, similar to Fig. 2, but with the plows lowered and in the ground, and r y 1 Figs. 4, 5 and 6 are details.

In the drawings I have showna plow having three plowing units comprising beams 1, 2 and 3, on the rear ends of which are mounted plows 4, 5 and 6 of a well known type; beams 1 and 3,1301 a portion of their length,

' converge toward beam 2 to which they are 8, the latter being braces rigidly connected by yoke shaped bars 7 and bolted to the beams and to a draftbar 9 which extends acrosslthe frontof the plow. The main frame 10 is supported by a land wheel 11 and front and rear furrow wheels 12 and 13. Mounted on the rear of the main frame 10 is a seat sup port 14 upon which a seat 15 is secured.

The beams 1, 2 and 3 are spaced apart by v 16 and 17 extending between the beams rearwardly and rigidly boltedthereto.

The plowis supported, forwardly by a lnto a spindle 27 which is swinging bail 18 having its ends bent parallel to the main frame and held in bearings 19 thereon; the bail 18 is preferably V-shaped and extends from the main frame downwardly and rearwardly, the bend of the bail being journaled in a bearing 20 on the end of a downwardly projecting bracket 21 secured to the beam 2. A bail 22 is journaled in a bearing 23 on the beam 1, and also in a bearing 24 011 an arm 25 rigidly secured on the beam 3. The forrowward end of the bail 22 is bent rearwardly and terminates in a lateral extension which is journaled in a bearing 26 on the main frame 10; the landward end of the bail 22 is bent similarly but the lateral extension thereof is prolonged journaled in a bearing 28 011 the main frame 10, and a similar bearing 29 on a supplemental frame 30 rigidly connected to the main frame 10 and extending landwardly therefrom.

A segmental member 31, preferably formed as a casing, is provided with a sleeve 32, ordinarily integral therewith, by which it is mounted on the spindle 27 to hold the member 31 rigidly on the spindle 27 I employ an arm 33, in this instance integral with the member 31, which extends to the rearwardly projecting portion of the bail 22 to which it is rigidly secured by a U-bolt 34 as shown. The arouate face of the member 31 is open except at the ends where it is closed by a web 35 at the upper end and by a similar web 36 at the lower end, both webs connecting the sides of the casing; the lower end of the member 31 forms a shoulder 37 which is adapted tocontact witha stop 38 rigidly secured on the main frame 10.

Pivotally mounted on a bolt or pin 39 in the member 31, adjacent the arcuate face thereof and substantially intermediate its length, are foot levers 40 and 41; the foot lever 40 extends upwardly, and its lower portion extends rearwardly from the pivot bolt 39 and has a notch 42 in the end thereof one side of which is adapted to contact with the web 36; the foot lever 41 extends rearseat 15, and forwardly from the pivot bolt 39, its forward end having a notch one side of which contacts with the web 35, and the other is adapted to engage with the underside of the stop 38." The notched s f wardly from the pivot bolt 39 towardthe the plow lowered end of 30operation, the mechanism 45 and to the beam lby 50 mounted on the spindle 5 ficiently strong to hold the levers 40 and 41 in operative position.

In Fig. 4 the levers in enlarged the sameupositionshown in Fig. .3, with and in operation; it is assumed that it is desired to raise the plow, which is lockeddown by the notch in the end'of the lever 41 engaging with the stop 38, the driver by pressure upon therear the lever 41 rocks it on its pivot 39 disengaging thenotched end from the stop 38 and bringing the lever 41 in contact with therweb: 37 of he member 31; continued pressure will rock the member 31 upwardly,

and as the'member 31 is rigidly connected to the bail 22,.the latterwill be rocked simultaneously in'the' same direction lifting'the plow'from' the ground; the downwardpressure upon thelever41 is continued until the notchin'the end of the lever 40 is abovethe top of the stop 38 with which it engagesautomatically by the tension of the spring 42; the pressure upon the lever 41 is now released and the plow is held raised and out of being in position as shown in full lines in Figs. 1 and :2, and in dotted lines in Fig; ,4.

Tolowerthe plow the'lever 40- is rocked until *the notch in the end thereof is disengaged fromthe upper side of the stop 38,

the bail 22 will be rockedin the opposite direction by the weight of the plow and the latter will descend to its operative position where it is-h'eld by' the notch in the end of thelever 41 again engaging with the stop 38,

as shown inFig. 3 and in Fig; 4. The ease of the operation of raising and lowering the plow-is materially aided by a coil spring 43 connected with the rear ofthe' main frame, one of the bolts which secures the bearing 23 thereto, the spring acting as a counter balance to the weight of theplow.

An auxiliary hand lever 44 is loosely 27 by means of a slot 45, formed in the lower end of a member 46 forming part of the lever 44, and through which the: spindle 27 extends; the lowenend of'the main portion of the lever 44 :isbent at aright angle and has aslot 47 which-is adapted to admit a pin-48 rigidly attached to the-spindleJQ'T. Thehand lever 44 is operable to raise or'lower the plow by engaging the slot'47 with the ,pin::48 and rockingthe ubail 22 after-thelock'by which :the plow is heldin position, has been broken Joy operating :the lever 40 i or 41 as the .case :may be. Thehandlever 44 can be moved out of .operativez' position by; sliding. it len'gthwise of the 40 and 41 areshowni detail in full lines and in inopposite directions, erable to rock sald'member-rand swmg the 47,when the lever can be rocked on the spindle 27 until it rests upontheframeBO where it can remain out of the way of the operator until again needed, a.
